It’s only been a week since Apple released iOS 6.1 to the public, and it’s already hard at work on the software’s next update. The iPhone-maker has seeded the first beta of iOS 6.1.1 to developers this morning, bringing the build to version 10B311.

It’s also worth noting that today’s beta arrives just 48 hours after the iOS 6.x evasi0n jailbreak was released. So obviously, those of you who are jailbroken that have access to today’s software update will want to avoid it until it’s investigated…

The release notes say that the new beta includes a number of improvements for the Maps app in Japan, including better pronunciation of roads during turn-by-turn navigation, updated icons for location categories and the addition of place data.

iOS 6.1.1 beta 1 includes the following improvements to Maps for Japan:

Improved pronunciation of roads during turn-by-turn navigation

Optimized directions to more strongly prefer highways over narrower roads
